Mercedes is the only team (as far as I know) that says things like "we win as a team and lose as a team", try to hold blame-free retrospectives, open collaboration between various sub-teams, and so on.
Every other team goes for cut-throat competition between individuals. "You have to prove yourself or you're out", mistakes are held against you, and so on.
Guess which team has won the last 8 constructor's championships?
I can't believe people aren't talking more about this.
